Patent DE-2933772-A1 (DE)
Title: Synthetic yarn false twister - has friction discs angled to each other to give stability and allow yarn twist reversal
Inventor: LORENZ HELLMUT DIPL ING
IPC: D02G1/08
Filed: 1979-08-21
Abstract: The two friction discs (1,2), rotating against each other to false-twist synthetic filament thermoplastics, are angled against each other so that the enclosed acute angle (Gamma) is open towards the yarn (6) travel direction. The discs are driven so that they have a movement component in the direction of yarn travel at the point where they make contact with the yarn. The design gives a stable yarn movement through the process, and yarn twist direction changes are possible.

Title: Heat engine with external heating and cooling - has closed flow of gas through heat exchangers moving piston by changes in density
Inventor: COST KARLFRIED
IPC: F02G1/04
Filed: 1979-09-12
Abstract: The engine has a central chamber (1) in which a piston (12) is moved up and down by the changes in the density of gas flowing past it. A fan (13) in the chamber blows gas in a closed loop through the chamber and through one of two side chambers (2,7). A valve (14) changes the flow from one side chamber to the other at regular intervals. In one side chamber (12) the gas is cooled by heat exchange (6) with an external medium and in the other side chamber (7) it is heated (11) by an external medium. The piston is connected to a crankshaft which also operates the valve (14).

IPC: D05B57/00
Filed: 1981-04-09
Abstract: The arm shaft (5), located in the sewing-machine arm (4), of the zigzag-stitch sewing machine carries on one of its ends a crank (26). The arm shaft (5) is driven in such a direction that it rotates in the clockwise direction, as seen in the direction of the shaft end carrying the crank (26). As a result of the rotational movement of the arm shaft (5), the needle bar (19) is driven in such a way that it executes, on the one hand, an up-and-down movement and, on the other hand, a sideways movement to the left and right in a plane extending perpendicularly to the axis of the arm shaft (5). The gripper shaft or bed shaft (39) is arranged rotatably in the sewing-machine bed (2) in such a way that it extends parallel to the arm shaft (5). However, in respect of the path of to-and-fro movement of the needle (21), the arm shaft (5) and the bed shaft (39) run away from one another in mutually opposite directions. The loop gripper (41), with the nose grasping the loop, rotates synchronously with the arm shaft (5), but in the opposite direction. The nose of the loop gripper (41) is arranged, in respect of the path of to-and-fro movement of the needle (21), on the side opposite the direction of extension of the bed shaft (39). <IMAGE>

Title: Knuckle joint for a vacuum cleaner nozzle
IPC: A47L9/02
Filed: 1981-08-07
Abstract: The invention relates to a knuckle joint on a suction nozzle for vacuum cleaners used, in particular for cleaning floors. A knuckle joint of this type consists of a knuckle shell (7) which is arranged in the housing (8) of the suction nozzle (1) and has a knuckle head (6) mounted in said shell. Provided on the knuckle head (6) is a receiving bush (5) to which a suction tube designed as a manual guide tube (4) can be attached.
